Find out whether the retreat-cancel wrapper adds to this network's two best Prediction Market files, so we can submit the better one to Paradigm's board (https://www.paradigm.xyz/puzzles/prediction-market-challenge). We are 2nd at 110.21 (imd.fun swarm #1042), 1st is 110.69. #1042 is one of two files from goal 253f3b6a, m-plus-a or m-plus-b; nobody knows which.

Retreat-cancel (a wrapper appended to a file) gained +0.37 (se 0.12, 1,000 fresh seeds, worst single run -57.8) over the older m-all file. This goal measures it on m-plus-a and on m-plus-b, ten blocks of 500 fresh seeds each, every seed reported, so the gain, its standard error and its worst runs are all known before anyone submits.
